S3-10DR

Product catalog summary

Overview: The S3-10DR is a 10kW three-phase power controller designed for DIN rail mounting with an IP20 rating. It is suitable for controlling resistive loads in electric furnaces and HVAC systems.

Features: The controller includes 0-10V input control, PWM control, zero crossover switching, auto/manual override, self-powered operation, and compliance with CE and BSEN50178 standards.

Specifications: The controller operates at a supply voltage of 415 Vac with a frequency range of 50-60 Hz. It has a maximum current of 14 A, losses of 26 W, and operates within a temperature range of -10 to +40°C. The unit is cooled by natural air convection and has a de-rating of 20% at 50°C.

Installation: The controller should be installed with heatsink fins vertically and requires specific clearances for ventilation. It is designed for plug-and-play installation, with a wiring diagram provided for guidance.

Operational Instructions: The controller regulates resistive loads by switching them on and off in time-proportioned bursts based on a 0-10Vdc input signal. It uses burst fire zero-voltage switching to minimize RFI and harmonic distortion.

Safety Instructions: A safety device must be installed to disconnect the mains supply in case of overheating. Suitable fuses should be used for cable protection, and the controller's internal fuses are for its protection only.

Testing and Maintenance: Proper insulation testing procedures must be followed to avoid damaging the thyristors. The unit should be tested by a qualified electrician due to the high voltages involved.

THYRISTOR CONTROLLER DATA SHEET S3-10DR 10kW Three Phase Power Controller - DIN Rail Mounting IP20 The Power Products range of S3 thyristor power controllers are designed for the control of resistive loads in electric furnaces, and heater batteries in HVAC systems. The S3 power controller series uses zero crossover switching. Burst Pulse Control ensures the load is switched only in multiples of a complete mains half-cycle in order to keep supply and electrical disturbance to a minimum. The units also feature variable frequency PWM for near infinite resolution. 0 - 10V Input Control 10kW Output PWM Control Zero Cross Over Switching AUTO / MANUAL Override Self-Powered DIN Rail (TS35) Mounting IP 20 Rating CE Compliant BSEN50178 Build Standard Specifications and Characteristics Type Number *Other Three Phase supply voltages may be accommodated - please enquire for details Power Products International Limited Commerce Way, Edenbridge, Kent T: 01732 866424 F: 01732 866399 [email protected] www.ppi-uk.com

THYRISTOR CONTROLLER DATA SHEET Operational & Safety Instructions OPERATION This power controller is designed to regulate a resistive load by switching the load on and off in time proportioned bursts according to the incoming dc signal (Factory set 0-10Vdc). LOCATION Install power controller with heatsink fins in the vertical plane. Allow a minimum of 100mm clearance top and bottom, and 25mm horizontally. Control panels should have sufficient ventilation (grills or louvres as required) to maintain the ambient temperature through the thyristor unit to below 40 Degrees C to run unit to specified...
